Abstrakt: An important portion of vitamins, minerals and polyphenols components in human diet are captured from fruit consumption. Argentinean Patagonia Berberis microphylla was characterized with the phenolic content, the proximate composition and the identification and quantification of anthocyanins, not-anthocyanins and proteins. The antioxidant capacity of berberis ethanolic extracts (EB) was determined by the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. EB was used to reduce production of reactive substances species (ROS) in zebrafish. EB presented a total polyphenols content of 1,035.03 mg GAE/100 g fresh weight (FW). EB presented an ABTS value of 116.25 ± 17 μmol TE/g FW. EB presented a DPPH value of 137.80 ± 1.90 μmol TE/g FW. EB was able of reducing the ROS in zebrafish. Berberies Protein Isolate (BPI) presented proteins with bands from 15 to 62 kDa. BPI presented an ABTS value of 593.11 ± 8.60 μmol TE/g. The BPI duodenal digest presented a value of 641.07 ± 12.60 μmol TE/g digests. PRACTICAL APPLICATIONS: The practical applications of the present study are to increase scientific knowledge for consumers about the quality and benefits of the consumption of the native fruit (Berberis microphylla) from the Patagonia region of Argentine. This work describes the protein profile of berberies, their digestibility and their antioxidant activity. This study allows to better understand the phytonutrients that make up this fruit. Future studies may identify the peptides present in hydrolyzates. The bio-compounds of this fruit could be used as functional ingredients by the food industry for different purposes.
